Mission NL8: F = m•a Calculations

Mission NL8 pertains to the use of the Newton's Second Law equation (F_net=m•a) to perform calculations of F_net, m, and a. The mission consists of 36 questions organized into 10 Question Groups. You must answer one question from each Question Group to complete the mission. The learning outcomes for this mission are ...
 

Learning Outcomes

• The student should be able to utilize Newton's second law equation to algebraically solve for an unknown quantity - acceleration, net force, or mass.
• The student should be able to analyze and interpret a free-body diagram and determine the acceleration of an object.

• In which direction does a friction force act?
• How can force information help one decide if an object is moving in a given direction and slowing down?
• If the net force on an object is leftward, does this mean that the object is moving leftward?
• What is the acceleration of an object which is moving with a constant velocity?
• How can one determine the mass of an object from force diagram information?
